Effectiveness study of sulfaclozine as anticoccidial drug by counting litter oocyst were carried out on a total of 12 broiler farms at Sirajgonj District in Bangladesh. For this study 12 broiler farms were selected randomly and kept under close observation for the natural outbreaks of coccidiosis in a period of one broiler crop grow out. Poultry rearing and farm management systems followed in all farms were almost same. Litter samples were collected following same procedure in every week throughout the experimental period both before and after treatment with four (04) commercially available sulfaclozine Na preparations. The number of oocysts per gram (OPG) of litter was calculated following McMaster method. Huge number of oocyst was counted after outbreaks but before treatment of coccidiosis in almost every farm and after treatment oocyst were found significantly (P ˂0.01) reduced in number. From the study it was concluded that use of sulfaclozine Na in the treatment and prevention of coccidiosis was found still now effective.
